I don't know if any other campuses have one, but at Middle Tennessee State University, the Chevy Gas Fairy has recently been spreading the great news about Chevrolet's current line of fuel-efficient vehicles. He rode in the Tahoe Hybrid for the homecoming parade a couple weeks ago and is showcasing a few new green Chevy cars on campus this Thursday.

pic 6 - they were playing musical chairs with the HHR to win gas cards.
pics 8 & 9 - it wasn't really the Malibu Hybrid, just the regular one with magnets on it.
